Support 31 mouse buttons (with platform plugins xcb and xlib).

Browse Source 
This commit includes changes for mouse button support within the XCB
and XLIB platform plugins. Support in other platform plugins will be
added in the future. The namespace update is prerequisite to compile
the the Plugins, and the update in qguiapplication.cpp is required for
the enhancements to actually work.
